Given numbers are 741,540,300,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,540,300,428 is 71358300.
Find LCM of 741,540,300,428 with Prime Factorization
| 2 | 741, 540, 300, 428 |
| 2 | 741, 270, 150, 214 |
| 3 | 741, 135, 75, 107 |
| 5 | 247, 45, 25, 107 |
| 247, 9, 5, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 247 x 9 x 5 x 107 = 71358300
Therefore, the lowest common multiple of 741,540,300,428 is 71358300.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
741 x 540 x 300 x 428 = 51377976000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
741 : 1, 3, 13, 19, 39, 57, 247, 741
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,540,300,428, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
540:2x 2x 3x 3x 3x 5
300:2x 2x 3x 5x 5
428:2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 51377976000/(1x720)
LCM = 51377976000/720
LCM = 71358300
Thus, we can understand that the LCM of 741,540,300,428 is 71358300.
